Application led March 7, 1910. Serial No. 547,842.

Be it known that we, JOHN B. HAoAwAr and JOHN V. ALLEN,citiz'ens of the United States, residing at Swampscott, in the.

county of Essex and Commonwealth of Massachusetts, and South Weymouth, yin the county of Norfolk and Commonwealth of Massachusetts, respectively, have invented certain Improvements in Machines for `Operating on the Sole Edges of' Boots al-d Shoes, of which the following descriptir, in lconnection with the accompanying dra ings, is a specification, like reference characters on the drawings indicating like parts in .the several figures. v

rlhis invention relates to machines for use in the manufacture of boots and shoes and particularly to a machine for operating on the marginal. portion of the sole of a boot or shoe.4 i

ln manufacturing welt shoes according to the usual practice the welt is'secured to the upper and insole by a line of stitches,.

known as the inseam, and thereafter the outsole is attached to the welt by another line of stitches, frequently termed the outseam, passing through the marginal p0rtions of the welt and outsole. The stitches of :the outseam lying upon the upper surface of the welt present an appearance which is objectionable in some grades of work, particularly in certain styles of womens shoes, and some manufacturers vtherefore have concealed the outseam by roughly trimming the sole edge so as to leave a lip protruding from the edge of y the welt and then turning this lip backwardly over the outseam with a hand tool of suitable shape and rubbing it down close to the upper surface of the welt. The shoe later was given its final trimming andthe turned over portion of the welt Wasv then wheeled or finished inv any other desired manner.

The general object of the present inven ytion .is to provide a machine for concealing the stitches of the outseam in a manner similar to that previously practised by hand.

The machine embodying the invention in its preferred form includes means for operating on the marginal portion of the welt of a shoe to force some of the stock backwardly and upwardly toward the upper,

and additional means associated therewith for acting on the stock so forced backwardly to crowd it in ,close to the upper and to smooth it down snugly over the stitches of the outseam. The. means first mentioned comprises a rotary tool of novel form, having the general shape of the frustum of a cone but provided on its lateral surface with a plurality of inclined ribs which decrease in height toward the Vforward end of the tool. This tool operates upon the welt to upset it and carry yportions of the stock backwardly over the outseam. The second means comprises another tool also of novel constructionand. a rotary hammer mechanism for operating said tool. The tool has im operatingface shaped to engage theedgI of the top of the welt and acts upon' the stock previously upset backtoward-the upper to crowd it down close to the stitches' of the outseam and to smooth off the upper surface of the welt.

The invention further provides novel work supports for each ofthe tools above described to aid the" workmen in presenting the shoe properly to the operation of the tools. The work supports shown are arranged for adjustment vertically, longitudinally and axially with reference to their respective tools and the`work support for the pounding. tool is arranged also to have a yielding movement with relationto said The. above and further features of the invention including certain details o f construction and combinations and 'arrange tion of a shoe having no welt.

In the accompanying drawings, Figure 1 is a front elevation of the head of a machine by the rotary tool to force it still further embodying the present invention; Fig. 2 is a side elevation of thel machine; Fig. 3 is a perspective view of the operatingmechanisms for theitools; Fig. 4 is a perspective view of the adjusting mechanism of the work support for the poun'ding tool, certain of the parts being broken away to show the inclosed devices; Fig. 5 is an end view of the rotary tool with the hub of the tool shown in section; Fig. 6 is,'a vertical sectional view of the pounding tool; Fig. V'i' is an exploded view of the pounding tool', its holder and the device by which it secured in the holder; and Fig. 8 is a perspec tive view showing the method of securing the upper work support in the frame of the machine. j l f The'supporting frame 2 is provided near its upper end with suitable bearings for the reception o'f a rotary shaft 4, which has attached to its rear end fast and loose pulleys 6 ,and 8 respectively. The shaft may b e driven by a belt running'on said pulleys and a`belt shifter 10 is provided for transferring said belt fromone pulley to the other. The forward end of the shaft is provided with a short screw threaded stud which receives the rotary tool 12. This tool is designed to engage the edge NofA the welt of a shoe to crowd portions of the stock backwardly toward the upper and for this purpose is given the general shape of the frustum of a cone-and is provided on its lateral surface with a plurality of ribs 14.

The ribs arev inclined to the elements of the lateral surface of the cone and decrease gradually in height from the smaller end of -the tool to the larger end, and the rearward sides of the ribs may be cut away as shown to form a more pronounced edge. The forward end of the tool is ground or rounded off so as to avoid any sharp edges that might injure the upper and this grinding axis of the rod and produces a more or less polygonal shape'as shown. While a variety of forms and shapes of tools may be employed Without departing from the spirit of the invention, the toolcshown has been found to produce very satisfactory results.

A`fwork support is arranged in operative relation to the tool 12 and comprises a rod 16 mounted in the frame and a split block 18 adjustably secured to the forward end of the rod by bolt 20. For the purpose of securing the rod 16 in adjusted position, a block 22 (see Fig. 8) .ispositioned in an aperture formed in the frame has one end shaped to engage the rod. A bolt` 24 extending through the block is adapted to force the block tightly against the rod 16 and hold the same against longitudinal movement. The rod is flattened on its lower side as shown in Fig. 3=for engagement with the surface of the bolt 24 and is thereby preat right angles to the.

ventedA from turning in the frame. Guideways are formed in the block 18 for the reception of a slide 26, a bolt- 28 being arranged to spring the split portions together to clamp the slide in an adjusted position. The slide 26 carries at its upper end a plate 30 having amare-shaped recess formed therein to constitute a bearing for one end of the roll 32 'designed to engage the tread face of the sole of a shoe presented to the operation ofthe tool 12. The other bearing for the roll 32 consistskof a stud 34 projecting from the lower end of the roll and received in a suitable aperture in the slide 26. The lower end of the stud is threaded to receive a nut and check nut to limit the upward movement of the roll. It should be noted that the for- Ward vertical faces of the slide 26 are beveled or inclined so that a shoe engaging the roll 32 may be rocked thereon to position it accurately with reference to the tool. By the construction described the Work support may be adjusted longitudinally in the frame, axially on the pivot bolt- 2O or vertically in the block 18 to accommodate varying thicknesses of soles and different styles of shoes.

The pounding tool hereinabove referred to is shown at 36 and comprises a shank portion adapted to be secured in the holder and an operating portion. The latter portion has. a shoulder 38 designed to engage the edge of the welt of a shoe and a projecting lip 40 designedto operate upon the upper surface of the' welt. The work ordinarily is fed past the tool from right to left and the width of the lip 40 is gradually increased in the direction of feed of the work, as indicated in Fig. 1, so that the widest portion of the .lip engages the top of the welt just before the welt leaves the tool. The ends of the shoulder and lip are rounded ott' so that the stock passes readily under the lip and shoulders. The outer face of the lip of the tool is beveled so that it may be forced into the crease between the welt and upper of a shoe. A slot 42is formed in the forward face of the shank of the tool to receive the head 44 of a T-shaped member, the shank 46 of which is secured in the lower split end of a holder 48. The split .portions of the holder arey clamped onto the shank 46 by a bolt 50.

l The operating mechanism for the tool 36 consists of a rotary hammer mechanism of the type disclosed in the United States Patent No. 768,560 granted August 23, 1904. This hammer mechanism is supported on and driven bythe shaft 4 and comprises a cage or carrier 51 scre wed onto the shaft and a series of rolls 52 mounted in the carrier. The holder 48 slides in a vertical guideway inthe frame, its upper end being normally below the path of rotation of the rolls; but when the holder is raised in its guideway by the engagement of the work with the tool, its

work support for the pounding tool is similar in general construction to that previously described. The work engaging member lconsists of a slide 56 having beveled orinclined faces and is mounted for vert-ical adjustment in a guideway formed in a split block 58. A bolt 60 binds the split portionsl onto the slide to secure it in adjusted position. The block 58 is mounted for angular adjustmentonthe forward end of a rod 62, a bolt 64 operated to hold the block in adjusted position. The rod 62 extends through.

the lower end of a supporting'bracket 66, depending from the frame 2, and has its upperside 4flattened to engage a transverse pin 68'Vsecured in the bracket which prevents angularmovement of the rod. It is desirable that this work support shall be capable of ready and accurate adjustment toward and from the pounding tool to accommodate varyingthicknesses of soles. Accordingly, means are provided whereby this adjust-ment may be effected merely by turning a hand wheel. Referring to Figs. 2 and4 4, the forked end of a member 70 is secured to the frame by a pin 7 2,'and this member has an enlarged screw threaded vportion 74 and a reduced extension 7 6projecting toward the tool 36. lThel adjusting wheel 78'has a cenl tral aperture to receive the rod 62 and is f the end of the rod 62 engages the inner face' provided with atubular extension 80 which is internally threaded near its end to en? gage the threaded portion 74 of the member 70. An enlargement orhead 82 formed on of the adjusting wheel and prevents the rod from sliding out of the aperture. Mounted loosely on the extension 7 6 of the member 70 is a nut 84 having external screw threads to engage the internal threads of the tubular member 80. A spring 86 surroundingthe extension 76 abuts at one end against the head 82 and at its other end against the nut 84 and tends to press the rod v62 and the. work support towardl the tool 36. The nut 84 may be adjusted to vary the tension-of the spring 86 by inserting a rod 87, indicated in dotted lines in Fig. 4, in-one of a'l plurality of pockets or slots 88 formed in' the upper surface of the nut andthen turning the nut to advance it toward. or withdraw it from the head' 82. 'A slot 90 formed in the member 80 permits the necessary an'-A gular movement of the rod ,87 to make the described adjustment.

toward or from the tool 36, it-` is.` necessary It will be j obvio'usthat to adjust the work engaging member 56l u nishmg. mac lne or 1n some other suit-able one direction or the other.v .The spring 86,

permits the work support to yield away from thev tool to compensate forV variations in the thickness of the Work. .l

It is usually preferable to give. the'sole edge a rough trimming` with a cutter shapedto leave a lip protruding from the edge `of .the welt as indicated at `a Fig.`2, before presenting-the shoe to the operation of this machine, The sole edge is then wetted and when suiicientlysoftened -is pres'nted tothe operation of the tool 12 in substantially the position shown-in Fig. 2. Asthe'- shoe is fed past the tool-from rightto left the ribs 14 catch the lip and turn or rub it backwardly and upwardly toward the upper into substantially the position indicated in said figure. 'Because of the greater height ofthe ribs at the smaller end of the toolv where they engage the lower portion of the. edge of the Welt land the upper edge of theV outsole, the'rubbing or upsetting action is greatest at this point, where,fof course, the stock resists the upsetting action more than at the upper edge of the'welt. The shoe with its welt thus partially turned back is next presented to the tool 36 which com .pletes the turning back operation. The

' shoulder 38 of the tool engages the edge of the welt and' the lip 40 engages the'upper surface of the welt. The shoe is fed p ast the tool from right to left, the narrow portion of thelip first engaging the top of the welt and the Widest 'portion operating' on the surface-"of the welt just before the shoe leaves the tool. This vportion of the lip preferably is wideenough to, extend intov the crease between the welt and upper so as to act upon the entire widthof the Welt.v The lipv thus operates progressively over the width of the welt as the shoe is fed past the tool. This tool not only exerts a further crowding and upsetting action upon the stock but also smooths down and consolidates the stock previously-acted upon by the rotary tool. l The operating face of the lip extends at an oblique angle to the shoulder l and therefore forms a uniformly' beveled surface around the entire forepart of the sole margin; at the same time it resses the stock down close ontothe stitc esv of theoutseam, thus effectually concealing them.

lIt is not essential .that the shoe be given a rough trimming to leave the 1i project- `ing from the Weltas vabove descrlbed to be preferable and many manufacturers prefer `to, turn Qback the Welt, in the manner set forth by operating vupon thev sole in thel shape 4in which itcomes from the-rough rounder. 'After the welt has been turned back and Asmoothed down, the shoe is given its inal'trimming and the-turned overwelt is finished u on a welt indenting and buriso Having described our'invention what we claim as ynewl and desire to secure byf'Letters Patent of .the United States is vl.
